Answer:
option 3
Explanation:
2x + 5y = 20
to bring this to a staffers equation with y on one side and everything else on the other, we see that we get a negative x term. that means the line goes down when going from left to right.
5y = -2x + 20
y = -2/5 x + 4
so, we also see that the y-intercept is 4.
so, option 3 is correct.
